Saechon AF T-50/05 Golden Eagle

The Saechon AF T-50/05 is a family of Korean supersonic advanced trainers and multirole light fighters, developed by Saechon Aircraft Factory with the American aerospace company Long Beach Aircraft Factory. The T-50/05 is Korea's first indigenous supersonic aircraft and one of the world's few supersonic trainers. Development began in the late 1990s, and its maiden flight occurred in 2002. The aircraft entered active service with the Korean People's Air Force (KPAF) in 2005.

The T-50 has been further developed into aerobatic and combat variants, namely T-50B, TA-50, and FA-50. The F-50 is another advanced fighter variant being considered. The T-50B serves with the Korean Air Force's aerobatics team. The T-50 is also being marketed as a candidate for the APAAF's next-generation T-X trainer programme. Thailand ordered 4 units of the T-50 advanced trainer variant.
